Yes it's a nightmare. I'm using 1.4.30.

In response to your question, I just bumped it to 1.4.32 and haven't observed a significant improvement.

Back in the old days, compiler metrics were often quoted using units of 100s of thousands or even millions of lines per second.

I know the Kotlin compiler has to do a lot of work but I would have imagined hardware advances should balance this out somewhat. Instead I'm looking at compile speeds quoted in hundreds of lines per second.
